Um to be honest Im not sure that the range is the best place to "meet guys". You'll probably talk to the guy that works there and thats about it.
I recommend joining gym with weighlifting fitness classes or crossfit or something - assuming you're already in ok shape. That would give a pretty good overlap of fit guys and girls. Join for a free or small fee trial period, check it out, and move on if you dont get what yourr looking for. In crossfit or fitness classes you have forced interaction, which creates a teamwork atmosphere. Easy to talk, plus easy to wear yoga pants or whatever else girl stuff that you use to fug with guys in the head. If you're medium hot you shouldnt have a problem. If you're super hot then you're might have to actively show interest. If you're fat, well now you're in a fitness class with a tyrone telling you what to do, so you'll get fitter.
PS If you do what I suggested expect to be hit on by literally every black guy. Just so you are aware.
Also maybe look into boxing and kick boxing. That is ussually lot of thots/skanks in yoga pants. Dont ask me how I know any of this btw.....
Edit: remember the free trial period! Dont sign a year membership. Again. Dont sign a year membership.
